What term describes a situation where a cartridge goes off without the trigger being pulled?

The correct answer describes a negligent discharge, which occurs when a firearm unintentionally discharges without the trigger being pulled. This situation can arise from various factors, such as mechanical failure, a faulty firing pin, or operator error. A negligent discharge highlights the importance of safe handling practices and the need for firearms to be treated as if they are always loaded. It is crucial for firearms instructors to educate students on the risks associated with negligent discharges and the proper procedures for handling firearms to prevent such incidents.

The other terms mentioned refer to different firearm-related issues: an out of battery issue occurs when the bolt is not fully locked, leading to a potentially dangerous situation; a misfire represents a failure of a cartridge to fire when the trigger is pulled; and a squib load refers to an underpowered cartridge that does not propel the bullet properly, potentially causing a blockage in the barrel. Each of these terms pertains to specific malfunctions or scenarios that differ fundamentally from the concept of a negligent discharge.
